As a specialized manufacturer based in Taiyuan, Shanxi, Shanxi Jurun Technology Co., Ltd. delivers precision-engineered DT44C cold-drawn pure iron bars designed for critical industrial applications. Our products combine exceptional magnetic properties with guaranteed mechanical precision, offering ±0.5mm/m straightness assurance that meets the most demanding specifications. With decades of metallurgical expertise, we've developed proprietary cold-drawing techniques that ensure consistent quality batch after batch.
The DT4C grade pure iron represents the pinnacle of soft magnetic materials, featuring:
Minimum 99.9% iron purity for optimal magnetic permeability
Ultra-low carbon content (
Controlled levels of sulfur, phosphorus, and non-metallic inclusions
Our cold-drawing process delivers unique advantages:
| Property | Specification | Benefit |
|---|---|---|
| Surface Roughness | Ra ≤ 1.6μm | Reduced machining requirements |
| Tensile Strength | 350-500 MPa | Structural integrity |
| Relative Permeability | ≥ 5,000 μr | Enhanced magnetic performance |
Key applications include:
Electromagnetic systems: Pole pieces, magnetic shields
Vacuum technology: Sealing flanges, chamber components
Research equipment: Particle accelerator components
The ±0.5mm/m straightness warranty ensures:
Reduced machining waste
Precision assembly compatibility
Minimal stress during installation
Shanxi Jurun Technology leverages Shanxi's rich metallurgical heritage to deliver materials trusted by tier-1 manufacturers worldwide. Our vertically integrated production facility maintains complete traceability from raw material to finished product. With dedicated quality control teams conducting 100% straightness verification using laser alignment systems, we stand behind every bar shipped.
FAQ Section
Q: How does the straightness warranty benefit my manufacturing process?
A: Our guaranteed straightness reduces secondary straightening operations, saving 15-30% in machining time and minimizing material waste in precision applications.
Q: What distinguishes DT4C from other pure iron grades?
A: DT4C offers superior purity (99.9%+ Fe) with controlled trace elements, resulting in exceptional magnetic saturation (2.15T) and minimal hysteresis losses.
Q: Can you supply custom diameters outside standard ranges?
A: Yes, we regularly produce diameters from 3mm to 200mm. Minimum order quantities apply for custom dimensions.
Q: How does cold-drawing affect magnetic properties?
A: Our proprietary process maintains optimal grain orientation, enhancing permeability while achieving precise dimensional control.
Q: What packaging options are available?
A: We offer VCI anti-rust paper wrapping, wooden crating, or custom palletization to ensure damage-free transit.
Q: Do you provide material certification?
A: All shipments include mill test reports with chemical composition and mechanical property data.
